Create a set of Level Notes by calculating the Elevations at the various Grid Points based on Grid Foresights shown.

$***$

Beginning Benchmark #$5$ value $=+73\mathrm{.}60\text{'}$ USC&G Datum

The Backsight value $=+5\mathrm{.}25\text{'}$

calculate the HI and the various Grid Elevations.

If the Foresight Reading on Benchmark #$10.$ what is the Vertical Error of Closure.

$=-3\mathrm{.}23,$ but the True Elevation Value of Benchmark #$10=75\mathrm{.}58$

Stationing should be labeled as A$1,$ A$2,$ etc.

Use $5-1$c Example of Differential Leveling Notes.
